SUMMARY:

This work addresses, demonstrates, and evaluates the relationship between urban morphology and photovoltaic solar energy generation, considering the legislation and urban planning parameters of the Urban Development Master Plan (PPDU - 2016) and the Laws of Zoning, Land Use, and Occupation (LOUOS - 2016) in Salvador. The research includes theoretical studies on photovoltaic technology, photovoltaic systems in buildings, and numerical models of cities related to energy. A literature review is also conducted on urban design, urban form parameters, and solar radiation availability. The experimentation involves creating generic models of urban sections based on the land use parameters that have the greatest impact on solar radiation in buildings (plot ratio, occupancy index, and building height). The modeling is done using the Rhinoceros software, and simulations of solar radiation on building surfaces are evaluated using the ClimateStudio plug-in. The simulations consider different scenarios, varying the plot ratio, occupancy index, and building height. These simulations were initially conducted with isolated buildings and later inserted into blocks without the surrounding context, highlighting the importance of considering the urban context in the analysis. Subsequent simulations maintained the same building standards but varied the distribution of buildings, including uniform distribution, non-uniform distribution, and random distribution within the block. The impact of urban density on solar generation potential was observed, with higher-density development having a greater impact. Additionally, in terms of individual buildings, lower-height buildings have a smaller impact on block positioning. A fourth scenario includes parameters for the Zone of Municipal Centrality 2 (ZCMu) with different building typologies. In this experiment, when taller buildings were positioned at the center and three corners of the block, the average and maximum values of average radiation were closer. Scenario 5 was based on the Occupation Pattern of Salvador, which represents existing patterns in the city's urban fabric, using the same block base as before. The analysis suggests that a balance between building density and height can result in better utilization of solar radiation. The last proposed scenario was based on a small section of the Pituba neighborhood, chosen for its potential for urban redevelopment and high level of verticalization. This case study demonstrated that altering the urban form, considering the current parameters, would have a negative impact on the average incident radiation for all buildings in the block.Thus, the research shows the need to establish stricter urban regulations that ensure urban form is designed to favor photovoltaic solar energy generation.
